CATHARINA GILBERTS, OF SAN FRANCISCO, CALIFORNIA.

MINCING-KNIFE.

SPECIFICATION forming part of "Letters Patent No. 279,643, dated June19, 1883. Application filed December 8, 1882. (No model.)

To all whom it may concern:

Be it known that I, CATHARINA GILBERTs, a subject of the Emperor ofGermany, and residing at San Francisco, in the county of San Franciscoand State of California, have in vented a new and useful Mincing-Knife,of which the following is a specification.

Figure 1 is a perspective view of my improved mincing-knife. Fig. 2-isan edge View. Fig. 3is'a vertical section through the fixed blade. Fig.4 is a side view of the central portion of the removable blade. Fig. 5is a perspective view, illustrating a modification.

Similar letters of reference are used to designate like'parts throughoutthe several views.

In the main blade 0, I cut two V-shaped notches, A A, and midway betweenthese notches I make an elongated vertical slot, B,

which extends to near the edge of said blade.

I11 this slot I place the transverse blade D, the center of which isprovided with a notch, E, which receives the square edge of the mainblade and holds the transverse blade in position, and prevents alllateral or side movement thereof. The slot in the transverse blade ismade deep enough to, allow the cutting-edge ofthe transverse blade to becarried down to a plane with the cutting-edge of the main blade, andwhen in position a key, F, holds it in place and prevents verticalmovement. From the V-shaped notches outwardly the main blade is maderounding much in the usualway, while midway between the notches theblade is somewhat fiattened, as shown. These V-shaped notches greatlyincrease the cutting capacity of the blades without requiring the bladesto be enlarged. By this construction four rightangled centralcutting-blades with flattened edges are obtained, and two endcutting-blades raised above the center blade, by means of which thecontents of the choppingbowl are operated upon around the sideszor abovethe center, which cannot be so readily acted upon by mincing-knivesconstructed in the ordinary way.

In the modlfication shown in Fig. 5 the gen eral construction of theblades will be the same. The upper edge of the removable blade isprovided with a notch, a, which receives the lower end of thesimilarly-notched slide 1), attached to the upper portion of themincingknife by means of a set-screw, c, which passes through the slot din the upper end of the slide. When it is necessary to remove thetransverse blade the set-screw is slackened and the slide I) raised upsufficiently high to clear the transverse blade, when it may be swungsidewise, and the blade raised still. higher, or until it clears thelower edge of the slot of the fixed blade, when it may be removed forthe purpose of resharpening.

\ I am aware that minoing-knives composed of several blades connected toahandle having a slotted and threaded shank by means of a screw-nut haveheretofore been used, but this I do not claim.

Having thus described my invention, what I claim, and desire to secureby Letters Patent,

- A mincing-knife composed of the blade 0, having notches A A and slotB, the transverse blade D, provided with slot E, and a key for securelyconnecting said blades, substantially as described.

In testimony that-I claim the foregoing I have hereunto set my hand andseal this 28th day of November, 1882.
